|
Function Imagick::morphology()- it is a built-in function in PHP that is used to apply a user-supplied kernel to an image according to a specified morphology method.

bool Imagick::morphology ($morphologyMethod, $iterations, $ImagickKernel, $channel = Imagick::CHANNEL_DEFAULT)
Parameters:This function takes four parameters as above and described below:
  • $morphologyMethod:this the parameter contains the morphology method to use.
  • $iterations:this parameter contains the iteration number to apply the morphology function.
  • $ImagickKernel:this parameter contains an ImagickKernel object.

The following programs illustrate the Imagick::morphology() functionin PHP:Program 1:  
/ / Create a new Imagick object $imagick = new Imagick ( https://media.engineerforengineer.org/wp-content/uploads/20190823154611/engineerforengineer24.png );  
// Create an ImagickKernel object $kernel = ImagickKernel::fromBuiltIn (Imagick::KERNEL_DIAMOND, "2" );  
// Apply morphology function $imagick -> morphology (Imagick::MORPHOLOGY_CONVOLVE, 2, $kernel ); header ( " Content-Type: image / jpg " );  
// Display the output image echo $imagick -> getImageBlob();  
?>
Output:
Program 2:  
// Create a new Imagick object $imagick = new Imagick ( https://media.engineerforengineer.org/wp-content/uploads/20190823154611/engineerforengineer24.png );  
// Create an ImagickKernel object $kernel = ImagickKernel::fromBuiltIn (Imagick::KERNEL_GAUSSIAN, "1, 2 " );  
// Apply morphology function $imagick -> morphology (Imagick::MORPHOLOGY_CONVOLVE, 5, $kernel ); header ( " Content-Type: image / jpg " );  
// Display the output image echo $imagick -> getImageBlob();  
?>
Output:
